CPAntennas Help Solve High School Theatre Drop-Out Problems

I purchased a pair of the CPAntennas over a year ago for the Klein Collins High School Theatre Department to use in our auditorium. I became familiar with your products after a fellow technical director in another school district recommended your equipment to me. I am forever grateful to my follow colleague for this suggestion. The IWxCPA antennas have been a true blessing.

We have played around with antenna placement for several years. From our control booth to the apron of our stage is just over 100ft. Normally we set up our sound gear in the middle of the house for our musicals and other large concerts. We run 16 to 24 wireless Sennheiser ew112 GA3 wireless microphones through our analog Allen and Heath GL3300 forty channel mixer. We run A, B and G frequencies. We have the traditional Sennheiser “Fin” type antennas. It seemed that no matter what we tried; we always had the odd ‘drop-outs. Now we did a thorough job of always placing new batteries in belt packs for every performance and making sure the transmitter antennas were placed correctly on the actors, checking frequencies, connections, etc. The problem would persist. It never seemed to fail that we would have at least one or two spots in the house or on stage where the signal would tend to be intermittent.

However, with the addition of the Kaltman Creations IWxCPA antennas and additional fine tuning of antenna placement we totally eliminated our “drop outs.” The spiraling pick-up pattern utilized by these Invisible Waves antennas has helped to eliminate those zones in our space we have had trouble with. It has been truly amazing. I can only credit this incredible “fix” to the addition of these Kaltman Invisible Waves antennas.

Hearing is believing! In fact, we have decided to purchase two more antennas to replace more of our “fin” style antennas. My fellow technical director also uses the Invisible Waves RF analyzer and has raved about how wonderful that cool little gem of a tool has been. That item will be in my next budget proposal.

In conclusion, Mark, your products are great! The customer service you provide is wonderful. How often is it that you can email a question to a company today and get a response from the president of the company? Initially this was the biggest and most unexpected of surprises. Talk about personal service…no other company does this! Thank your for your great products and great service. Keep it up!
